I agree, I don't think the rehabilitation centers really do much. Maybe 1 out of every 1000 people or so, the person changes because of the rehabilitation center but for the most part I think it's a waste of money and is really unrealistic that these centers will really have a big impact on a murderer. However, I think the murderer know that their lives are going to suck after they kill someone regardless of the death penalty and they probably don't care too much about the punishment because they don't have much to lose or don't think they'll get caught.
